Lamplit vs Flo
The Flo alternative where cycle data stays on your device
Flo is the category giant — the biggest content library, pregnancy mode, and real perimenopause support. It also carries the category's history: a 2021 FTC order over health data shared with advertising SDKs, a $59.5M settlement cluster resolved in 2025, and US-hosted data. If that history is why you're searching, this page is for you.

Why people look for a Flo alternative
The record, precisely: the FTC alleged Flo shared users' health data with third-party SDKs including Facebook's and Google's (2016–2019); the order was finalized in June 2021. In 2025 a jury found Meta liable for receiving Flo users' data, and Flo, Google and Flurry settled for a combined $59.5M without admission of wrongdoing.
Anonymous Mode is opt-in, not the default — and independent 2026 testing found a device identifier reaching an analytics partner before it was enabled.
Your data lives in the US on AWS, per Flo's own help center — and is therefore subject to US legal process.

Where Lamplit takes a different approach
Private by architecture, not by promise
Lamplit computes cycle predictions on your device, and when your pattern is irregular, predictions pause rather than guess. Cycle data is structurally unshareable — no feed path, no partner codes, no export-to-friends exists for it. Core cycle tracking is free, permanently.
The cycle in whole-body context
Phase analysis sits beside your sleep, training and mood data — and on Max, training coaching that weighs your cycle phase. Flo logs lifestyle factors as symptoms; it can't see your training plan or your sleep trend.
Perimenopause, in context
Credit where due: Flo shipped a real perimenopause mode in 2025, and Clue did in 2023. Lamplit's differs by living inside whole-health tracking — sleep disruption, HRV shifts and mood tracked as first-class data alongside the cycle, not as symptom checkboxes.
What Lamplit deliberately doesn't do
Lamplit is not a fertility, conception or contraception product, and makes no fertile-window claims. Trying to conceive? Use Flo's TTC mode or Clue Conceive. Want app-based contraception? Natural Cycles is the only FDA-cleared option. This boundary is by design.
Who Flo is genuinely best for
- You're on the trying-to-conceive → pregnancy → postpartum journey (Flo's strongest suite)
- You want the biggest content library and expert articles
- Partner sharing matters to you
- The anonymous peer community (Secret Chats) is valuable to you
Who Lamplit is best for
- Privacy drives your choice: on-device predictions, structurally unshareable cycle data, EU hosting
- You track sleep, training and mood — and want your cycle understood in that context
- You're in perimenopause and want it tracked with whole-body data
- You want core cycle tracking free, permanently
Other Flo alternatives worth considering

Berlin-based and science-first, with the strongest privacy record among the big trackers.
Natural Cycles
The only FDA-cleared app-based birth control.
drip
Open-source, local-only cycle tracking.

Switching from Flo
Flo can export your data from its settings. In Lamplit, enter your last few period dates and typical cycle length — predictions calibrate within a cycle or two, and pause when your pattern turns irregular instead of guessing. On Pro, HealthKit / Health Connect import can backfill history.
